Why the study?
Does physiologic stimulation of sensorimotor cortex elicit normal regional cerebral blood flow responses in patients with severe carotid artery disease?
Does physiologic stimulation of sensorimotor cortex elicit normal regional cerebral blood flow responses in patients with severe carotid artery disease?
In patients with severe carotid artery disease, regional cerebral blood flow responses during physiologic tasks may not reliably indicate local neuronal activity.

rCBF responses to sensorimotor tasks may not reliably indicate neuronal activity in severe carotid disease; hypothesis-generating and requires validation.
Powers et al. (1988) studied this question.
